Newest first. This is the tail of the record — for every retired tool with its date, reason and replacements, read the full graveyard listing.
OpenAI deprecated the Assistants API after achieving feature parity in the Responses API. It will shut down on August 26, 2026. Existing integrations should migrate to the Responses API using OpenAI's official migration guide: https://developers.openai.com/api/docs/assistants/migration
use instead: LangChain, LlamaIndex, Vercel AI SDK
GitHub repository archived by Charm; last observed push was 2026-03-09 and no further development is expected.
use instead: Warp, Aider
Official Continue site states that Continue has been acquired by Cursor; standalone Continue is now maintained as historical/graveyard context rather than an active independent coding assistant.
use instead: Twinny, JetBrains AI
Original codeball.ai product domain no longer represents the Codeball PR-triage tool; pricing/app surfaces unavailable; public GitHub Action appears legacy.
use instead: CodeRabbit, Graphite, Panto AI
Rebranded to Devin Desktop on June 2, 2026. The core IDE, Cascade agent workflows, configuration, and subscription tiers continue directly under Devin Desktop.
use instead: Kiro, Trae, Google Antigravity
Legacy Windsurf plan branding was folded into Devin Desktop on 2026-06-02; windsurf.com/pricing now redirects to Devin pricing.
use instead: Cursor Plans, Kiro Plans, JetBrains AI Pro
Roo Code extension was shut down on May 15, 2026. The official RooCodeInc/Roo-Code GitHub repository is archived, the final VS Marketplace release is v3.54.0 from May 15, 2026, and roocode.com now redirects to Roomote. The original team pivoted to Roomote; new IDE-extension users should evaluate Cline or the community ZooCode fork instead.
use instead: Cline, Kilo Code
JetBrains discontinued Fleet on December 22, 2025, refocusing the platform into JetBrains Air — a new agentic development product in preview. Distribution ended via Toolbox and direct download. Existing AI work continues across IntelliJ, PyCharm, WebStorm, and other established IDEs through JetBrains AI Assistant.
use instead: GitHub Codespaces, Gitpod, StackBlitz
Humanloop team joined Anthropic and official migration docs state the standalone Humanloop platform was sunset on September 8, 2025, with accounts and associated data scheduled for deletion after that date. Keep this page as historical/migration due-diligence content, not as an active SaaS recommendation.
use instead: Langfuse, Helicone, W&B Weave
Acquired by Google in May 2025 and rebranded as Google Stitch, launched under the Google Labs umbrella as an AI app builder powered by the Gemini model family. Galileo AI no longer operates as a standalone product — the original usegalileo.ai site now redirects users to Stitch, and former users can import their conversation history into Stitch through the settings page, though imported chats are view-only and cannot be continued. The core UI generation engine now runs on Gemini and benefits from Google's infrastructure, with deeper integrations for Figma export and front-end code generation. Co-founders Arnaud Shen and Helen Zhou joined Google as part of the acquisition.
use instead: Relume, Figma Dev Mode, Anima
WhyLabs discontinued its managed SaaS operations. Core open-source profiling libraries remain available, while teams needing active production ML observability and LLM tracing use Evidently AI or Arize Phoenix.
use instead: Beszel, TensorZero
Acquired by AWS in 2023 and rebranded as Amazon CodeWhisperer for command line, then folded into Amazon Q Developer. Standalone Fig was fully discontinued on February 19, 2025. AWS gutted the community-driven autocomplete specs and replaced them with a proprietary AI layer. A cautionary tale of acquisition-by-sunset — the acquirer wanted the team, not the product.
use instead: Atuin, Fish Shell
